I am trying to load an image and extracting some other details from a website in WebView
from an url by inserting it in html code but when I try to load an image it shows nothing but an question symbol in WebView
.
我试图通过插入html代码从URL中加载图像并从WebView中的网站中提取其他一些细节但是当我尝试加载图像时,它只显示WebView中的问题符号。
here is some part of the code
这是代码的一部分
String htmlDetails(String extract) {
String desc, link;
String cost, model, ratings, specifications;
Document document = Jsoup.parse(extract);
extract = document.text();
Elements description = document.select("a");
Elements img = document.select("img[src]");
Elements modelvalue = document.select("h2[class=a-size-base a-color-null s-inline s-access-title a-text-normal]");
model = modelvalue.text().toString();
Elements costvalue = document.select("div[class=a-row a-spacing-mini]");
cost = costvalue.text().toString();
Elements ratingvalue = document.select("div[class=a-row a-spacing-none]");
ratings = ratingvalue.text().toString();
Elements specificationvalue = document.select("ul[class=a-row a-spacing-top-mini a-spacing-mini]");
specifications = specificationvalue.text().toString();
desc = description.html();//attr("content");*/
desc = img.attr("src").toString();
desc = desc.substring(2);
link = "http://10.0.2.2/andro/"+desc;
String Html = "<html>"
+"<body>"
+"<img src='"+link+"' width='30px' height='50px'/>"
+"</body>"
+"</html>";
return Html;
}
webview.lodaData(htmlDetails(HTML_String), "text/html", "UTF-8");

A couple of hints:
一些提示:
Check if your app has INTERNET
permission. WebView doesn't show any error messages, it just silently fails to load network stuff if you don't have this permission in your manifest:
检查您的应用是否具有INTERNET权限。 WebView不会显示任何错误消息,如果您在清单中没有此权限,它就会无声地加载网络内容:
<uses-permission android:name="android.permission.INTERNET" />
And you may need to use WebView.loadDataWithBaseUrl
and specify your server's address in baseUrl
argument:
您可能需要使用WebView.loadDataWithBaseUrl并在baseUrl参数中指定服务器的地址:
webview.loadDataWithBaseUrl("http://10.0.2.2/", htmlDetails(HTML_String), "text/html", "UTF-8", null);
